RADAR SENSOR, MOTOR VEHICLE, AND METHOD FOR OPERATING A RADAR SENSOR
A radar sensor for a motor vehicle, in particular a passenger car, is disclosed. The radar sensor has a control unit, an antenna arrangement, and a reflector device for reflecting transmitted radar signals from the antenna arrangement into a measurement region and radar signals, which are to be received by the antenna arrangement from the measurement region. The reflector device has a parabolic reflector. The control unit is designed to change the measurement region by changing the radiation characteristic and/or the reception characteristic, in particular by beamsteering and/or beamforming, during control of the antenna arrangement such that various reflection regions of the reflector device that correspond to different measuring regions are used.
Distributed radar sensor system
A radar sensor is described herein. In accordance with one example embodiment the radar sensor includes a transmitter for transmitting an RF signal and a receiver configured to receive a respective back-scattered signal from at least one radar target and to provide a corresponding digital radar signal. The radar sensor further includes a processor configured to convert the digital radar signal into the frequency do-main thus providing respective frequency domain data and to compress the frequency domain data. A communication interface is configured to transmit the compressed frequency domain data via a communication link operably coupled to the communication interface. Furthermore, respective and related radar methods and systems are described.
Vehicular radar sensor with mechanical coupling of sensor housing
A radar sensor for a vehicular radar sensing system includes a housing structure and at least one printed circuit board (PCB). The housing structure includes a front housing and a rear housing. The PCB is accommodated between the front housing and the rear housing in a cavity established when the front housing and the rear housing are joined together. The rear housing may be joined to the front housing via an intermediate frame disposed between the front housing and the rear housing, with the rear housing secured to the intermediate frame via a plurality of fasteners and with the front housing secured to the intermediate frame via welding.
Vehicle and method of controlling the same
A vehicle includes a sensing device disposed at the vehicle so as to have an external field of view of the vehicle, configured to detect a target vehicle moving from the external field of view to a parking space and a plurality of stationary parked vehicles; a controller configured to obtain a first distance that is a width between the plurality of parked vehicles and a second distance that is a width between one parked vehicle of the plurality of parked vehicles and the target vehicle adjacent to the one parked vehicle; and a warner configured to output a warning signal based on a control command of the controller.
MOUNTING STRUCTURE OF OBJECT DETECTION DEVICE TO VEHICLE BODY
The disclosure provides a mounting structure of an object detection device to a vehicle body capable of improving the accuracy of object detection by the object detection device and improving the durability of the object detection device. A mounting structure of a radar device, which is an object detection device for detecting objects, to a vehicle body includes: a support bracket attached to the vehicle body side for supporting the radar device in a first direction, which is an object detection direction by the radar device; and a cover member fixed to the first direction side of the support bracket and disposed on the first direction side of the radar device. The radar device is housed in a housing chamber defined by the cover member and the support bracket.
Resettable tranceiver bracket
A resettable bracket is herein presented. The bracket is configured to mount a transceiver to a vehicle. The bracket includes a first piece and a second piece configured to be pivotably connected to each other. A docking station is mounted to the first piece. The docking station includes a bluff, an over-travel stop, and a plurality of arms configured to restrict pivotable movement of the second piece in relation to the first piece. A fitting element is mounted to the second piece. The fitting element is configured to dock into the docking station to substantially create the pivotable connection between the first and the second piece. A spring is installed at the pivotable connection between the first and second pieces. The spring is configured to allow the second piece to automatically return to a default position after being pivoted in relation to the first piece.
Method of, and apparatus for, operating a vehicle
A method of operating a vehicle wherein the method comprises using a distance sensor to determine the distance between a part of the vehicle and an object, and implementing a speed control procedure if the distance detected by the distance sensor falls below a predetermined value, characterized in that the method is implemented only while the vehicle is in reverse gear and for a period of time immediately following disengagement of the reverse gear.
Flexible radar support for absorbing vibration deviation
A flexible radar support for absorbing vibration deviation comprises a support base and a support top cover that are engaged with each other in an interlocking manner. A housing space for arranging a radar is formed between the support base and the support top cover. The support base includes: a centrally arranged base center, and a base edge circumferentially arranged around the base center. The base edge and the base center are connected through four flexible structures that form U-shaped cantilever beams protruding towards the support top cover. With the flexible radar support provided, and with the design of U-shaped flexible structures, where an automobile body vibrates at a large amplitude, the flexible radar support can still absorb swaying in the up and down, and left and right directions during the course of driving, thereby reducing the impact of the automobile body's vibrations on the detection precision of a radar.
RADAR APPARATUS AND BUMPER STATE DETERMINATION METHOD
A radar apparatus includes: a transmission processor, which, in operation, transmits first wave signals from inside of the bumper toward outside, the transmission processor being provided inside of the bumper; a reception processor, which, in operation, receives an object-reflected wave signal that is a reflection of the first wave signals by a target in an area around the vehicle, a bumper-reflected wave signal that is a reflection of the first wave signals by the bumper, and a transmission and reception leak signal of the first wave signals and detects the target through the object-reflected wave signal; and a bumper determiner, which, in operation, detects a first reception level of a second wave signal including the bumper-reflected wave signal and the transmission and reception leak signal, compares the first reception level with a threshold, and determines the presence of a bad bumper state in a case where the first reception level is higher than the threshold.
RADAR SYSTEMS AND METHOD FOR BACKING A TRAILER
A RADAR system and associated methods are used to detect obstacles obscured from view when backing a trailer. An autonomous tractor is equipped with a rear facing RADAR device that has a field-of-view under the trailer and is configured to output RADAR returns from reflections. A controller of the tractor classifies RADAR returns from the RADAR device according to a number of reflections by a dock wall and a trailer face (e.g., a back end of the trailer) of a corresponding RADAR beam. The RADAR returns are correlated based on distance, and distance of a RADAR return from an obstacle is corrected based on the number of reflections. Advantageously, by processing RADAR returns from both direct and reflected RADAR beams, the controller is able to detect obstacles hidden behind the trailer and flag the obstacles as a hazard.
